Conjuring a Battleaxe, usually isnt a problem.....Unless your in combat, and haver to cast a new one, or cast it for the 1st time, after enemies are actively after you...It casts the spell, goes through the motion, charges you the magicka, but when he appears to be holding a 2handed axe, theres nothing there... You cannot swing it, you cannot "sheath" it, trying to equip other weapons do not work, as theyll not appear after this happens, and 'sometimes' you can get it to stop by dual wielding spells...Otherwise, you must reset the game...

This is pretty annoying, as your running away from, and dodging attacks wqith no way to defend yourself, or kill enemies... Potions that heal are your only option until you figure out how to get it unstuck...This is pretty much a 100% chance to happen, and doesnt happen with either of the 2 other bound weapons...I can ALWAYS duplicate this bug, and its only once in combat...This is an old bug for me, and just thought id post it...

Sorry if its known already
